Postbit table issue

[roxics]

I always have difficulty with tables. For some reason these aren't lining up right:

Here is my code:

PHP Code:

<table bgcolor="{pagebgcolor}" width="{tablewidth}" cellpadding="0" cellspacing="0" border="0"><tr><td width="10"><img width="10" height="1" src="{imagesfolder}/space.gif" alt=""></td><td width="100%"><!-- spacer -->
 

<table cellpadding="{tableouterborderwidth}" cellspacing="0" border="0" bgcolor="{tablebordercolor}" {tableouterextra} width="{contenttablewidth}" align="center"><tr><td>
<table cellpadding="4" cellspacing="{tableinnerborderwidth}" border="0" {tableinnerextra} width="100%">
<tr>
 <td bgcolor="$post[backcolor]" width="175" valign="top" nowrap>
 <a name="post$post[postid]"></a>
 $post[firstnewinsert]
 <normalfont><b><a href="member.php?s=$session[sessionhash]&action=getinfo&userid=$post[userid]" target="_blank">$post[username]</a>
</b></normalfont><br>
 <smallfont>
 $post[avatar]<br>
 <a href="editpost.php?s=$session[sessionhash]&action=editpost&postid=$post[postid]">Edit</a> | 
   <a href="newreply.php?s=$session[sessionhash]&action=newreply&postid=$post[postid]">Quote</a></smallfont><br>
 
 
 </td>
 
 <td bgcolor="$post[backcolor]" width="100%" valign="top">
 <smallfont>$post[icon] <b>$post[title]</b><br>Posted: $post[postdate] - 
 <font color="{timecolor}">$post[posttime]</font> - 
 $post[editedby]</smallfont><hr>
 <p><normalfont>$post[message]</normalfont></p>
 <smallfont>$post[attachment]<br>
 </smallfont>
 
 </td>
</tr>
  </table>
 
</td>
</tr>
</table>
</td></tr></table> 


Attached is a screenshot of the problem. See how the inside table doesn't line up with the outer table.
